Documentation/gradle tasks out of date

[dragbone]

The documentation and/or gradle tasks of kool-basic-template seem to be out of date:

• ./gradlew runApp doesn't exist, should probably be ./gradlew runJvm
• ./gradlew build only creates distribution for javascript (readme says it creates jvm and js)
• javascript distribution (dist/js) is missing the assets from the asset folder (BoxAniamted.gltf and kool-test-tex.png)

Thanks, haven't checked that in a while. Updated.
